Design
The Don Valley Mk1 Chain is a positive improvement over traditional design, and has resulted from many years practical experience, designing and building scraper conveyors plus an extensive knowledge of the operational problems associated with the transportation of bulk materials where particularly arduous conditions exist. Mk1 Chain offers the following advantages to the user :-

Forged Cross Bar Connecting Links form an integral part of the chain and provide a strong and reliable connection to the flights, eliminating the possibility of weld failure at this critical point.

Easily Replaceable Cross Bars are tailored to suit individual requirements. These are bolted direct to the forged connectors with High Tensile Bolts and Re-useable Locknuts. The interfaces of the mating surfaces are also chemically bonded together during assembly to provide enhanced security.

Rationalisation of Spares. Capital outlay and replacement costs are minimised since :-
Chains and Connectors are symmetrical and not handed. Provided that the Cross Bar pitch is constant, a single strand of chain held in stock will serve as a spare for any number of conveyors regardless of flight bar length or design.
In the event of localised damage, the individual component can easily be replaced.
Assembled lengths of chain are connected on site by cold riveting.

bulletCross Bar Fixing Kits with full instructions are available to enable the customer to undertake refurbishment or repair work.
